Furthermore, city life fosters social interaction and connections with new people, unlike smaller towns or villages.

Software Myths:Management Myths:

Ambiguity - when a single event or expression can mean two different things to two different people

Modern and Contemporary Art: Scam or Genius?

"Is contemporary or modern art a scam or a stroke of genius?" This is a common question. Although this is considered art, for me, it is not.

On the one hand, when you see a work of art from other eras, such as Romanesque art, regardless of your personal tastes, the work behind the artwork is appreciated. In return, when you look at a work of contemporary art, although you look and look, you find nothing, and it often comes with disproportionately high prices.

On the other hand, a few years ago, the BBC did a test. They put three works regarded as true works of art and three works made by children together. The result was curious: the work that received the most votes was made by a child, and many experts... Continue reading "Modern Art vs. Solidarity vs. Entrepreneurship: Insights & Analysis" »

Phishing:

Hackers attempt to impersonate genuine organisations to fool the user into providing sensitive personal data. Emails are very official-looking, and they usually contain a link to a website which is an exact copy of the organisation's actual site, but it is operated by the criminals. When the user logs in with their details, the data is sent to the criminal. 

Guarding against phishing:

No reputable organisation would request personal details in an email or unsolicited phone call, because it does not need your sensitive data to access your account information. Never follow links to a bank/organisation- manually type it.

Trojan Horses:

Malware program that comes in disguise. Rely on tricking the user into downloading and running them. Involves... Continue reading "Protecting Against Phishing, Trojan Horses, Worms, and Viruses" »

What They Mean by Original Sin

The concept of original sin suggests that everyone is born with a predisposition towards wrongdoing, a desire for temporary pleasure or fulfillment. This inclination, while often diminishing with maturity, leaves a lasting impact on the human psyche. Consequently, our actions, purpose, and intentions become central to our moral compass.

St. Augustine's Perspective on Desire and Evil

St. Augustine, reflecting on his own youthful temptations, recognized a connection between desire and moral evil. Inspired by the simple life and virtuous intentions of St. Antony, he underwent a personal transformation, aspiring to become a better person.

Roald Dahl (1916-1990)

British Author of Norwegian Descent

Roald Dahl was a British novelist and short story author of Norwegian descent. He achieved fame as a writer for both children and adults.

Early Life and Influences

Some of his most famous works include Charlie and the Chocolate Factory, The Witches, and Kiss Kiss. In 1920, tragedy struck when his 7-year-old sister died from appendicitis, followed a month later by his father's death from pneumonia at the age of 57. Dahl attended several boarding schools, an experience he found unpleasant due to homesickness, leading him to write frequent letters to his mother. The inspiration for Charlie and the Chocolate Factory came during his time studying in Derbyshire, where pupils tasted chocolates....

Human Eye Structure and Function

Key Components:

• Conjunctiva: Thin, transparent membrane lining the front of the sclera. It's moistened by tears, produced in the tear glands, which contain lysozyme, an enzyme that kills bacteria.
• Pupil: Opening in the iris through which light passes. It controls the amount of light entering the eye and appears black due to the black pigment of the choroid.
• Lens: Clear structure that allows light into the eye. It's made of stiff jelly and can change shape to focus light.
• Iris: Colored part of the eye that responds to light.
• Cornea: Transparent, protective layer at the front of the eye.
• Suspensory Ligaments: Fibers supporting the lens. When pulled tight, the lens is thin; when loosened, the lens is thicker.
• Ciliary Muscles:
